The apparatus also includes optical fiber cores each extending from the second side through a corresponding cavity and protruding axially at the first side. The axial protrusion tapers from a first diameter down to a second diameter. The apparatus additionally includes a light emitter optically connected to the optical fiber cores and configured to emit light thereinto. A cut-off size associated with the light is greater than or equal to the second diameter such that an evanescent electromagnetic wave is generated at the cut-off portion. The apparatus further includes light detectors each being optically connected at the second side to a corresponding optical fiber core and configured to measure an intensity of the light reflected from the cut-off portion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Evanescent wave based optical profiler array","description":"An apparatus includes a support structure defining therein substantially parallel cavities extending from a first side of the support structure to a second side of the support structure.
